If you could have any piece of new technology as an infantry soldier what would it be and why?

I'm not an Infantryman, but I can say from my days of humping a ruck and an aid bag, less is more. Every time someone wants to stick a new gadget or monitor on you, it's more stuff to get tangled up in. If there was one thing that I wish had been invented it would have been lighter, thinner, more breathable armor. Army is always going to come up with more gadgets, sensors, radios, rescue equipment, drones, and robots for your to carry, plus all their batteries. So if you can have thinner lighter armor it's easier to carry

An M-16 that had the guts of a AK-47, in doing so, it wouldn't have jammed alot when fouled up with carbon.
But we dealt with it in the infantry, most don't know it, but the forward assist did what it was supposed to do. It got the round seated in the chamber, but your M-16 would still only shoot one round at a time, until cleaning, that's if you had the time too.
All the optics, and laser stuff, why have it, when you could call in indirect fire, or an air strike, or just get online and mop up the area.

I'm old-school, so the technology that I would want wouldn't be anything bleeding-edge, it would be making whatever I have to carry and use more reliable, and more durable, without making it more unwearable, CPT Enrique M..
